Hi Doug

Yes, the early Model 90 receivers had push-pull Type 45 outputs.

Then Philco switched to a single ended Type 47 pentode output.

Finally, in early 1932, Philco changed the 90 again, to use push-pull Type 47 outputs.

I honestly do not remember if I ever said that the cathedral 90 sets did not have push-pull Type 47 tubes; but if I said that, I was wrong.

Examples do exist of Model 90 cathedrals with push-pull Type 47 outputs; enough so that not all of them could have been switcheroos from 90X consoles.
